Instructions
- Step 1: Preheat oven to 400°F (200°C). Pat beef tenderloin dry with paper towels and season evenly with 1/2 tsp sea salt and 1/4 tsp black pepper.
- Step 2: Heat 1 tbsp avocado oil in an oven-safe skillet over medium-high heat until shimmering. Sear beef for 3 minutes per side until golden-brown crust forms.
- Step 3: Transfer skillet to oven and roast for 12-15 minutes for medium-rare, or until internal temperature reaches 125°F (52°C).
- Step 4: Remove beef from skillet and let rest for 10 minutes. Meanwhile, melt 2 tbsp butter in the skillet over medium heat, add minced garlic, and cook for 1 minute until fragrant without browning.
- Step 5: Stir in chopped rosemary and thyme, then pour the butter mixture over the rested beef and let it absorb for 2 minutes before slicing.
